Method of Producing Hydraulic Oil

Abstract

A single hydraulic oil with improved operational properties is proposed. This oil is based on a fraction of paraffin-free petroleum which boils in a 220-312C range, has a viscosity of 2-2.2 cSt at 50C and 160-180 cSt at -50C, a solidification point no higher than -70C, and an aniline point of 66- 66.5C. By adding to this base known viscous, antioxidant, and anticorrosion additives, a hydraulic oil is produced with particularly favorable low- temperature characteristics, which assures the functioning of the hydraulic oil in a temperature range of from -55C to 90C and has high anticorrosion properties and a high antioxidant stability.
